5 In the accompanying Figure 1 is a front specific form.

Figure 2 is a cross-section from the line II,II

in Figure 1.

'5 3. Figures 3 and 4 are drawings, elevation of the above respectively top plan and vertical cross-sectional views of detailsfrom the first two figures.

Figures 5 and 6 are vertical cross-sectional views of a modification of the invention.

3 Figures 7 to 10 modification, and

Figure 11 is a diagram inclusive, illustrate a further of the inventions wiring.

' A vertically reciprocable cross-head 1' is car- 2, and a plurality of spindle holders 3 are adjustably clamped to this cross- .-head by bolts 4 having T- heads engaged in slots 5 :m the head. These heads each carry a pair of spindles 6 which hold punches '7'.

These punches ,are each opposed by the-usual dies 8 which are .shown about to adjustable to register with them. A beam 9 is be punched, hold-down rollers 10 preventing it from being lifted by the punches.

Each of the in the spindle 5 are unimpeded holder 3 spindles 6 telescopes into bores 11 and when their paths are inoperative because they will freely rise in the bore 11 during the downward I punching stroke of the h ead 1. This may be prevented by gags or blocks 12 which slide in guide- "ways opening into these 'so they may slide about bores and have slots 13 the bolts 4, thus holding ENT OFFICE" their motion within their working limits. The I conventional and perfectly using machinery of this of the gags carries a frame 14 having a cut-out portion 15in its outer end, and a bar 16 extends the width of the crossback and forth in the cutthe latter being here disclosed. 1

Thus, the ends of the shaft 18 have short arms 19 which are urged upwardly by springs 20 and carry rollers 22 which contact cams 22 stationarily fixed to the punchs frame. These cams are suitably shaped to impart the desired motion and are preferably constructed with a rather abrupt working face 22 so that the shafts re ciprocation occurs in a quickand snapping manner.

From the above it will be noted that each gag carries an extending frame 14 having a'cut-out portion in which the bar 16 continuously reciprocates in the proper directions and at the proper times to move the gags into and out of their blocking positions so that the punches'operate. Proceeding, each frame carries a pivoted arm 21 21 which engages the may be attracted constructed so that their contacts just span the distance between each central plug and one of those surrounding it in the case of each group, and the central ones of these jacks are continuously energized while those surrounding these central ones are selectively energized by push buttons. This circuit is diagrammatically shown with a storage battery 29 as the energizing force, although in actual practice the system will prob ably be connected to a low power line. For convenience, the individual wires are carried through a conduit 30 fixed to the reciprocating element and a second conduit 31 fixed to the frame of the punch, a flexible conduit 32 interconnecting these two.

The construction of the various not shown because any type may groups of push buttons are shown in view because the modern multiple erally includes two lines of punches.

When it is desired to adjust the spindle holders of the punch laterally it is only necessary to pull the plugs from the jacks, adjust the holders in the usual manner, and reinsert the plugs in the closest group of jacks. The gags may be operated in any sequence desired by proper insertion of the plugs in the respective jack groups. Thus, if several holes are to be punched at once in a number of instances, the respective plugs associated therewith are insertedin the same positions in'the respective groups. Then, when the button is pushed which energizes those particular jacks, the entire group of gags will be simultaneously shoved into place. Also, should it become necessary to change the operating sequence of these punches thus associated, it is a simple matter to individually shift the plugs to another set of jacks in each group, and the push buttons 28 will then cause the punches to operate in this changed sequence.

.Another form of the gag operating device above specifically described may consist of a frame 33 fixed to the gag 12 and engaging the rod 16 through links 34 and 35. At each stroke of the bar 16-these links buckle upwardly and downwardly and no motion is imparted to the frame 33. The link 35 carries an armature 36 which downwardly by a solenoid 3'7 fixed to the frame 33 and energized in the manner described in connection with the first construction. When this energizing occurs the links will be prevented from buckling upwardly and the gag will be moved into punch-operating position. when the solenoid is energized, a lug 34 on the link 34 releases a latch 34 which otherwise engages a stop 34.

In this, form the bar 16 is preferably reciprocated in a perfectly horizontal plane instead of an arcuate direction. This motion may be obtained by inserting links 38 between the bar 16 and, its driving fingers 17 and providing the frames 33 with flattened surfaces 39 on which'it can slide.

.Another form may consist in eliminating the round bar 16 and providing a flat bar 40 which slides on horizontal guides 41. This bar is driven by the fingers 1'? through su'table links which may be the same, generally speaking, as those shown in connection with the above modification. The bar 40 is provided with a longitudinal slot 42 which mounts frames 43. Each of these frames mounts a solenoid 44 and is fixed to the bar 40 through its slot by a bored and externally threaded portion 45 on which a securing nut 46 is screwed. This bored bolt portion slidably carries push buttons is be used. Two the elevation punch genhind said spindle,

' jacks, means for energizing 'means on said gag a plunger 4'? which passes through the solenoid 44 and terminates with an armature 48. A compression spring 49 is arranged about this plunger through the solenoid 44 so as to urge the armature 48 away therefrom. Each of the gags 12 is provided with a U-shaped coupling element 50 which cooperates with an inverted U-shaped coupling element 51 on the inner end of the plunger 47.

Preferably, the frames threaded portion 45 is of rectangular form where it passes through the slot 42 so that it may be held against rotation from its proper position.

The action of this last form is as follows. When the fingers 17 reciprocate the bar 40 the plunger maintains a stationary position because as the bar moves forwardly the compression spring 49 will keep this plunger in its gag retracted position. However, as soon as the solenoid 44 is energized it will hold the armature 48 when brought therewith by the backward movement of the bar 40, and will carry it along as the bar moves forwardly, causing the plunger 4'? to move the gag into spindle-blocking position.
